I think the above should be possible, but IMO there is a simpler way, 
which is to configure appropriately the rsync daemon on the 
destination/server machine.  To do this:

1)	Configure one or more appropriate rsync 'share(s)' or virtual 
drive(s) for the backup files.  This is usually done in 
/etc/rsyncd.conf, but for embedded boxes other possibilities might be 
/etc/config/rsyncd.conf or /opt/etc/rsyncd.conf  -  for example:

# rsync daemon configuration
pid file = /var/run/rsyncd.pid
hosts allow = 192.168.1.0/255.255.255.0, 169.254.0.0/255.255.0.0
# Quite possibly other global options as required

[BackUp]
         path = /path/to/backup/location
         comment = PC backup files

2)	Start rsync as a daemon at PC boot time.  Traditionally this used to 
be done by a script in /etc/init.d, and still is here in Ubuntu 22, but 
nowadays might be via something like systemctl.  Manually a suitable 
command-line might be something like:

/usr/bin/rsync --daemon --config=/etc/rsyncd.conf

Then, from the source PC, you can just type or create a script 
containing something like (note the trailing slashes on both source and 
destination paths, and beware unintended line-wrap, this should be all 
one line):

rsync [usual options as desired] /source/path/with/trailing/slash/ 
rsync://user@server/BackUp/sub-path/as/desired/with/trailing/slash/

Notes:

If the user requires a password, then you can specify that in the script 
environment using the variable RSYNC_PASSWORD.  For better security, you 
can specify an rsync-only user and password combo in the conf file using 
(I'm afraid I can't remember how to find the encrypted version of the 
above password string to set here, but most probably I got it from the 
man pages):

rsync user = whoever
rsync enpswd = whatever # (must be encrypted to match what is in plain 
text in the RSYNC_PASSWORD variable used by the rsync command)

AFAICR, the rsync protocol encrypts data during transit without needing 
recourse to ssh, but you may wish to check my ageing memory on that point.
